Archos forum / Does Your Pma400 Take This Command?

« on: March 13, 2006, 12:06:44 pm »

Hi All,

    I'm trying some simple stuff on my PMA400. It's strange to see that the sound card /dev/dsp doesn't work very well.
    I started a terminal, and tried $cat somesoundfile > /dev/dsp. This playback worked well. However, the recording command, $cat /dev/dsp > soundfile, didn't record anything. I opened this output soundfile with a audio editing program, it showed a flat line. BTW, all hardware recording settings were good.
   Does your PMA400 works well on this command?
   Help guys help.

Qt/Qtopia / Pma400 Sdk And Qtopia 1.7 Sdk Linking Error

« on: March 10, 2006, 03:24:54 pm »

I've solved the problem myself. Ironically, I found some useful information from a French website; even worse, French and I don't know each other very well. Anyway, i copied libqte.2.3.6 from /opt/Qtopia.rom/lib on Archos PMA400, which is the lower version of current libqte supplied in Qtopia 1.7 SDK. And i changed the links to point libqte.so.2.3.6 instead of libqte.2.3.7. After that, the compiler complained that libz is required, however, this libz doesn't exist in both PMA400 SDK and Qtopia SKD. I found it on the Archos PMA again under /usr/lib. Eventually, the problem solved. Hope this is helpful to whoever has the same problem.
